Application filed March 81, 1922. l Serial No. 548,334.

To all whomt'zf may conce/ML:

Be it known that we, LEo F. OFLAHERTY and WILLLAM L. KIRKPATRIGK, citizens of the United States, and residents of the city of Elgin, county of Kane, and 'State of Illinois, have invented certain new-andvuseful Improvements in Valves, of which the following is a specification.

This invention relates to valves', and more particularly to valves for mixing hot and cold water, or other fluids, and has for its object the provision ofv a valve having means for actuating thesame, saidactuating lmeans being independently operable to seal said mixing valve.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter-.described and claimed. y

The invention will be best understood by reference to the accornpanyingv drawings forming a part of this specification, and in which,

Fig. 1 is Va vertical sectional view ofthe invention, showing the same in inoperative or sealed position. v Y

Fig. 2 is a fragmentary vertical sectional view of the invention showing 4the same in one operative position, the sealing means being unseated to permit the passage of fluid therepast. f

Fig. 3 is a view, partly in section, on the line 3-3 of Fig. 1,

Fig. 4 is a detail sectional view of the mixing valve proper.

- Fig. 5 is a detail view of the sealing valve,

mounted on the mixing valve operatingv means.

Fig. 6 is a sectional view on line 6-6 of Fig. 5. 1 A

Fig. 7 is a fragmentary sectional View showing one relative position of the mixing valve. f

Fig. 8 is a similar View showing another position of the mixing valve when the" same has been rotated a small distance in an anticlockwise direction.

Fig. 9 is a similar view showing the 'position assumed by the valve on further antiolockwise'rotatiomand Fig. 10 is a similar view showing lthe position assumed by the valve on still further anti-clockwise rotation.

The invention lcomprises a casing 10, preferably having inlet ducts 11 and 12, and an Outlet duct 13. Such casing is preferrection of course effects ably divided into mixing chamber 14, and

a discharge chamber 15, by means of a partition 16, threaded into shoulders 17, on the inner periphery of the casing 10, the partition 16 preferably being provided `with an aperture 18, such aperture preferably being surrounded by lan annular rib 19, asshown.

Preferably rotatably mounted in the mixing chamber 14, `is a cup-shaped `valve 2U having suitable ports 20"in its periphery, as shown, such valve also preferably being provided with an upstanding boss 21, such boss preferably having therein anlangular bore 22. i

Mounted in the discharge chamber a threaded bearing member 28, such bearing v member preferably being supported on lshoulders 24 in the interior of the casing 10.

Washers 25 are preferably disposed upon the bearing member. 24,-and such washers and said bearing memberare held in position by means of a cap 26 threaded onto the casing 10, as shown. i

Threaded v'nto the bearing member 24 is a stem 27, the outer end of which carries inner end 29 of .which is preferably reduced and shaped to slidably project 'into the boss 21, vas shown. A sealing valve 30 ispreferably mounted on the stem 27 as shown,vand in the innermost position of said stem v-is adapted torest upon and snugly engage the rib 19 on the partition 16.

By this arrangement, when the stemv 27 is rotated, such rotation is transmitted to the cup-shaped valve 20 inorder to mix lfluids entering the chamber 14 throughthe inlets 11 and 12, the rotatable movement of such stem serving to lift the sealing valve 30 off its'seat, to permit the passa-ge of fluid `a handle28 for rotating the same,and the through the aperture 16 and thence from the both of theinlets and then with the other tioned inlet. This movement also raises'thesealing valve the greatest distance from` its seat. Rotation of thestem in opposite dia reverse operation ofthevalve. -Y v'- While we have illustrated and described the preferred form of construction for carrying our invention into eect, thisl is such variations and modifications as come within the scope of the appended claims.

Having described our invention; what we claim as new and desire to secure by Letters Patent is: l

l. A mixing device comprising a casing; a partition dividing said casing into communicating mixing and discharge chambers; a mixing valve in said mixing chamber having an angular socket therein; a stem mounted for sliding movement in said socket, and adapted to impart rotation thereto; and a seal-ing valve in said discharge chamber mounted on and movable with said stem.

2., A Vmixing device comprising a casing; a partition dividing said casing 'into' communicating mixing and -discharge chambers; a mixing valve in said mixing chamber having an angular socket therein; a rotatable .stem mountedl for longitudinal movement, having its end slidably but non-rotatably engaging said socket, whereby rotation of said stem causes longitudinal movement thereof and rotation of said valve; and a sealing valve inv said discharge chamber mounted on and movable with said stem.

3. A mixing device comprising a casing; a partition dividing said casing into mixing and discharge chambers and having an aperture therein; a valve mounted in said mixing chamber for rotative movement only; means longitudinally movable adapted to rotate `said valve; and sealing means in said discharge chamber and mounted on said longitudinally movingmeans for closing said aperture.

4. A mixing device comprising a casing; a partition dividing said casing into communicating mixing and discharge chambers; amixing valve in said mixing chamber and capable of rotative movement alone; means mounted in said discharge chamber and projecting into said mixing chamber Iadapted to rotate said valve; and sealing means in said discharge chamber mounted on and movable c with said rotatable means and adapted to close the communication between said chambers.

Y'5. A mixingdevicel comprising a casing; apartition dividing said casing into communicating mixingl and discharge chambers; a mixing valve rotatably mounted in said `mixing chamber; a stem .mounted in said discharge chamber and projecting into said mixing chamber adapted toslidably engage said mixing valve and rotate same; and a sealing valve in said discharge chamber mounted on and moving with said stem and 6. A mixing device comprising a casing;`

a partition dividing said casing into communicating mixing and discharge chambers;

a cup-shaped valve having mixing ports in its periphery; a central boss in said valve; a

Astem mounted in `said. discharge chamber and slidably and non-rotatably engaging said boss; and a sealing valve in said discharge chamber mounted on and movable Withsaid stem for closing 'the communication between said chambers..

7. A mixing devicel comprising a mixing chamber; a mixing valve mounted in said chamber tor rotative movement only; means projecting into said mixing chamber for operatin0` vsaid valve and bein(T so arranged that rotation of said means rotates said valve, and simultaneously causes said means to travel longitudinally; and means lupon said operating means adapted to open and close said 1iiixing chamber during the travel of said operating means. y

8. A mixing device comprising a casing having mixing and dischargel chambers;- a

lmixing valvemounted in said mixing chamber for rotative movement only; means mounted in saidv discharge chamber aindgprojecting into said mixing chamber and adapted to rotatesaid valve; and sealing means in said discharge chamber mounted on and movable with said rotatable `means Sand soV adapted to close communication between said chambers.

9. yA mixing device comprising communicatmg mixing and dischargeffchambers; Va

' bearing in said discharge chamber ;a mixing valve in said mixing chamber; a stem threaded in said bearing and slidably but non.- rotatably engaging said mixing valve; and a sealing valve mounted on and movable with said stem and adapted vto close communication between said chambers. y

l0.` A mixing device comprising,.communicating mixing and discharge chambers; a bearing in said r(ilischarge chamber; a,y cupshaped mixingy valve in said n'iixing chamber, said valve having Va central boss :therein; a stem threaded in said bearing and slidably and non-rotatably engaging said boss; and a sealing valve mounted onand movable with said stem to closethey communication between saidv chambers.` A

yIn testimony whereof we have signed our names to this specification` in. the lpresemce of two subscribing witnesses.
